Abstract

In the algebraic grid generation, mixed schemes define a smooth transformation from the parameter domain into the physical domain M32_ContiMorandiSpitaleri0.png, that is M32_ContiMorandiSpitaleri1.png. The Boolean sum guarantees boundary conformity, while M32_ContiMorandiSpitaleri2.png provides more degrees of freedom by means of the control points. On the other hand, if we need more control points in a specific part of the grid to locally control the grid, we are forced to add control points also in to the two strips intersecting each other in the region of interest. Thus, we propose the use of a class of functions such that only their restrictions in the subsets are tensor product functions. [DOI: 10.1685 / CSC06055] About DOI
